Kernel: KVM: error in exception handling leads to wrong debug stack value

A flaw was found in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first...

USN-3641-1: Linux kernel vulnerabilities

Nick Peterson discovered that the Linux kernel did not properly handle debug exceptions following a MOV/POP to SS instruction. A local attacker could use this to cause a denial of service system crash. This issue only affected the amd64 architecture. CVE-2018-8897 Andy Lutomirski discovered that...
